What vehicles are most commonly affected by C0733?
This code is frequently seen in models like the 2015-2019 Ford Explorer, as well as other Ford vehicles from similar years. Always check for any recalls or technical service bulletins related to the steering system.
How can I prevent C0733 from happening again?
Regular maintenance of your vehicle’s steering system, including wiring inspection and sensor checks during routine services, can help prevent issues with the steering angle sensor.
What is C0733?
DTC C0733 is a diagnostic trouble code that indicates a malfunction in the steering angle sensor circuit. This code is particularly common in vehicles like the 2015-2019 Ford Explorer. The steering angle sensor provides critical data to the vehicle's stability control system, informing it about the angle at which the steering wheel is turned. When this sensor fails or reports an erroneous signal, it can lead to issues like loss of traction control, difficulty in steering, and a warning light on the dashboard. In practical terms, if you're experiencing this code, you may notice your car's handling is not as responsive, and the check engine or stability control warning lights may illuminate. Ignoring this issue can lead to further complications, including more severe steering issues and compromised vehicle safety. Therefore, it’s essential to diagnose and address the cause of this code promptly to ensure safe driving conditions.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0733 is present:
- The check engine light stays on constantly, indicating a fault that needs attention.
- The vehicle may exhibit erratic steering behavior, making it difficult to maintain control while driving.
- Fuel economy may decrease by 10-15% due to the engine management system working harder to compensate for the steering error.
- You might experience the stability control light activating intermittently, especially during turns or slippery conditions.
- In some cases, you could encounter a message on the dashboard alerting you about a steering system malfunction.
Possible Causes
Most common causes of C0733 (ordered by frequency):
- The most common cause is a faulty steering angle sensor, with a likelihood of about 70%. This sensor may become damaged due to wear or exposure to moisture.
- Another common cause is damaged wiring or connectors in the steering column, which can disrupt the sensor's signal to the ECM.
- Improper alignment or steering system components that have been altered can lead to inaccuracies in sensor readings, potentially leading to C0733.
- Less common but serious causes may include a malfunctioning electronic control module (ECM), which could misinterpret the sensor's data.
- A rare cause could be software issues within the vehicle’s stability control system, which may require a software update to resolve.
